description.

This invention relates to computing and accounting machines, and has forits main object to provide a cash register having as an attachmentthereto a computing scale.

a The invention contemplates a combined machine of the type referred to,in which a cash register may be used separately to perform all itsordinary functions, or the computing scale may be used to determine theentry of the transaction in the cash register.

The invention further contemplates the use of a well-known cash registernow on the market, as to which no novelty is claimed herein, inconnection with a computing scale having novel features in itself, andso connected to the cash register that the amountdetermining devicesthereof may be set automatically to an amount indicated by the computingscale without further effort on the part of the operator.

The invention also has for,its object to provide a computing scale onwhich the amount of a purchase may be indicated, and the amountthenadded into the cash register or not as the operator chooses.

A further object is to provide an alters native controlling means forthe computing mechanism. In many cases it will be desired to compute aproduct, one of the factors of which is a quantity, such, for eX- ample,asanumber of yards of cloth. In such cases, of course, the scale will beof no advantage. There is therefore provided an alternative means, theembodiment of which in the present machine is a pointer adapted to bemanually moved over a scale, and in its movement to exercise the samecontrol over the computing mechanism as that exercised byv the scale.Interlocking means are provided between the quantity indicator and thescale,'whereby if either is moved, the other .is locked from operation.The quantity indicator when used is designed to take precisely the partoccupied by the scale in the device.

With these and incidental objects in View,

the invention consists in certain novel features of construction andcombinations of parts, the essential elements of which are set forth inappended claims and a preferred form of embodiment of which ishereinafter specifically described with reference to the drawings whichaccompany and form part of this specification.

Of said drawings: Figure 1 is a plan view of the combined machine. Fig.2 is a rear elevation of same, with the casing removed.

Fig. 7 isa diagrammatic view of the three-cent amount-determining disks. Fig. 7is a detail of the zero setting devices. Fig. 8 is a plan view of aquantity indicator. Fig. 9 is a vertical section of the same. Fig. 10represents an enlarged partial rear elevation of the machine with theframe containing the sub-counter removed. Fig. 11 represents an enlargedrear elevation of the frame containing the sub-counter. Fig. 12 repre-'sents a detail sectional view taken on line" 12'12 of Fig. 11. Fig. 13represents an enlarged section through the sub-counter frame.

Described in general terms, this invention adapted to abut whenreleased. When the determining disks have been set and the crank handleor other operating means is operated, the controlllng barsmove to aposition determined by the graduations on the peripheries of thedetermining disks, and thereby set up on a sub-counter an amountdetermined by the weight on the scale and the rate per unit of weight.This latter factoris provided for by a series of keys which are adaptedto release the proper controlling barsandpermit them to move.

. meanwhile reset to normal position.

.When the amount is set up on the sub-counter, as referred to, a furthermovement of the handle causesthis amount to ,be transferred to theregister-controlling devices of.

the cash register, the sub-counter being This ends the; first stageofthe operation, the product having been computed and set up on the cashregister indicating devices, and all the usual functions of a computingscale are thereby performed, inasmuch as the operator can then see theproduct desired.

A further movement of the handle will now cause theusual operation ofthe cash register. If, on the other hand, it is not desired to enter thetransaction in the cash register, as, for example, if the customerdecides not to complete the purchase, the machine may be left just as itis, with clerks'indication showing. Another quantity may be placed onthe scale, when the above referred to operation may be repeated. It willthus be seen that the machine may be used as a simple computing scale,or it may be used to automatically register the amounts de-v termined bythe scale.

Inasmuch as-Smanytransactions would involve a quantity of material,such, for example, as, a number of yards of cloth, this of course couldnot be computed by the scale, and therei's, therefore, provided analternative means for controlling the computing devices, consisting of alever movable over a scale, and servin to actuate when desiredthecontrolling dis referred to. The operation when the quantity indicatorisused is the same as that with the scale; that is,

the quantity point'er'is movedto a position depending on the number ofunits of quantity,"and the keys representing the rate per unit are alsodepressed.' An operation of the crank'handle then completeslthe movementof, the mechanism.

531v the term computing mechanism u throughout this specification andthe claims, it is intended to cover any form of mechanism whereby theproduct of a plur'ality of factors may be determined and by the termrate mechanism it is intended to cover an form of mechanism fordeterminingthe actor used in the computation corresponding to the rateor price per unit of I vers '11, loose the article to be-sold, as priceper pound or peryardn The cash're'giste'r to which the invention isshown as adapted is best shown in .Fig. 6. It comprises nerall'y aseries of setting'le- .journaled on a rod 12, and

rigid with sai levers'are-segments 13, gearing with rack bars 14. IThese rack bars each has a counter operating rack 15' and an indicatoroperating rack 16 thereon. The settin levers 11 each carries ananti-friction me It thereon. The setting levers 11 each;

the indicator pinion 24 and the indicator 25.

Inasmuch, however, as in the ordinary operation of the machine a flashor shutter is arranged to cover indicators 25, the small clerksindicators are proviged, which are alas an indication ways visible, andwhich ai 4 of the position of the levers. A counter 31 is mounted in amovable frame 32, arranged to slide in a second frame 33. This counter31 is adapted to be moved downward and back at each operation of themachine, thereby engaging one or more of the teeth 15 on the rack bar14, and causing the operation of the counter. This counter is more fullydescribed in United States patent to Thomas Carroll, No. 751,611.

Fig. 3, and comprises a scale pan 41, supported on a lever 42 by a knifeedge 43. Lever 42 is also pivoted on :a knife edge 44, and is adaptedthrough a link 45 to rock lever 146, journaled on a pin 47 in the frameof.

the machine. Movable with lever 146 is a segment 47, attached to whichby a lost motion action is a rack bar- 48. The purpose of the lostmotion connection is to prevent back lash between the rack-teeth of thesegment andthe teeth of a pinion 49. A sprin 50 connecting the segment47 and the mo bar 48 serves to draw the rack bar in one direction.

The scale used in the machine is shown in As shown in. Fig. 2, thepinion 49 is car-- 4 ried by a transverse shaft 50, extendin across theback of the machine. This sha t carries "a number of determining disks51, also shown in Fig. 5, which are adapted to limit the movement of aplurality of com.

trolling bars, there being one bar for each disk. These bars are bestshown in Fig. at '52, and are normall elevated above the. I

highest part of the peripheries of the disks. They are held latched bysuports 53, all of which are journaled'on a r are depressed. To accomplishthis purpose, each key is provided with a pin 56, adapted to engage andmove the cam edge 57 of a longitudinal bar 58. This bar h'asa notchthrough which the support 53 moves, and it is evident that a forwardmovement of bar'- the proper support 53' forward 58 will carr (l therebyrelease the controlling with it, an bar 52.

54. A plurality of rate per unit keys 55 are adapted to release saidcontrolling bars when the keys As shown in Fig. 1, there are a V of rateper unitkeys, arranged in banks and adapted to compute. amounts, atprices varying from one-fourth'of a cent up to 59 3/4 cents. As shownthe scale is adapted to weigh amounts up to 25 pounds, so that itproduct to be computed will include four denominations. .This,therefore, renders necessary the use in some instances of fourcontrolling disks 51, corresponding to a rate per unit key. As shown inFig. 2, one disk for the one-fourth cent key, and two disks for each ofthe keys from one-half to and including three cents; three disks foreach of the keys from four cents to and including thirty cents, and fourdisks each for ling bars 52 are severally adapted to gear with one of aplurality of pinions 59, 60 or 61, shown in Figs. 2, 6 and 13. Inaddition to these pinions, provided for the fourth or $10 controllingbar used in connection with the and cent keys.

' After the controlling disks have been turned to correspond to-theweight on the scale, the proper rate per unit or price keys aredepressed, and this releases and allows to drop the proper controllingbars 52. These bars drop differentially, depending on the positionsofthe controlling disks. two disks connected with the three-centcontrolling bar are shown separately in Fig. 7. In this figure thecontrolling bars 52 are also indicated. There are two disks inconnection with the three-cent key, one with a series of short steps forthe units. denomination of the product, and the other with a series oflong steps. It will be seen by a study of the first mentioned disk thatit is 40 calculated to give the store proprietor the advantage of allfractionsof a half cent or over, and to give the purchaser the advantageof all fractions less than a half cent,

but it will be evident that to change this principle would simply .needsome slight cljanges in the relative positions of the steps. As anexample of the use of the device, it may be pointed out that at thepoint marked 15,the units disk is depressed five steps, and the tensdisk depressed one step. The disks would be moved to bring this pointunder the controlling bars 52 when five pounds is placed onthe scale,and when the controlling barsthen drop the units bar will move five.steps, and the tens bar one step. At the point marked 45, the bars 52will drop, the tens bars dropping four steps and the units bar droppingfive steps. disks will be brought under the controlling bars 52 whenfifteen pounds is placed on the scale. The point marked 63 willevidently be brought under the controlling disks by a weight oftwenty-one pounds, and in such case the controlling bars 52 will drop,the

units bar dropping three steps, and the tens will be evident that thehighest possible there is the forty and fifty-cent keys. The control-'extrapinions 62 and 63 are The This point on the bar dropping six steps.Further examples might be given, but it is thought that these three willbe sufficient to illustrate the operation of the device, the position ofthe steps being merely a matter of calculation. It will of course beevident that the the different amounts must be calculated separately,and will in most cases be unlike each other. Y

It would of course be possible to hold the rate per unit keys indepressed position by the pressure of a finger thereon, but there isprovided a detent means for doing this. Beferring to Fig. 4, the rateper unit keys 55 are shown as each carrying a pin 66. These pins areadapted to move when the'key is depressed through cam slots 67 in adetent bar 68, thereby moving the detent bar against the tension of areturn spring 69. Near one end of the detent bar is a bar 7 0, bestshown on Fig. 6, at a right angle with the bar 68. When the bar 68 ismoved to the left in Fig. 4, bar 70 will be released and moved forward xunder the tension of spring 71 and lock detent 68 in its new position,thereby retaining the rate per unit keys depressed. Bar 70 is at the endof the first part of the operation retracted to release the keys bymeans which will be described later.

The mechanism for entering the computed amounts on the sub-counter willnow be described, with reference to Figs. 5 and 6. When the rate keys 55are depressed, moving bars 58 forwardly, projections 72 on said bars areadapted to engage and move disks for a rod 73. The rod 73, as shown inFig. 5,

is carried by frame arms 74 which also carry a pin 75 moving in a slotin the lower one of two links 77. The lower link 77 has a cam slot 78adapted to move past apin 79 mounted in the main frame and the upperlink 77 provides means for controlling conamount I As will from Fig. 5,a gear wheel 81 is journection and disconnection of the operatingdevices of the machine. be seen 'naled on a shaft 82 and is adapted togear with a larger wheel 83 journaled on a floating shaft 84, which alsosupports the ends of the two links 77, and is further adapted to gearwith anoperating gear wheel 85. The upper link 77 also carries a stubshaft 86 on which is journaled a gear wheel 8-7 also adapted to meshwith operating gear 85. The shaft 84 carries a link 91 connected toshaft 82 and a link 92 connects the shaft 86 with the shaft 93 whichcarries a gear wheel 94.

Rotation of the shaft 82 occurs when the gear 83 is in mesh with thegear 85 and causes reciprocation of the counter 31 over the racks 15 andthe addition on said counter of an amount corresponding to the settingof the racks 15. the register is effected by the lever 237 which isconnected at one end to the counter frame The reciprocation of ingshownat'the to n ecting gear 87 thereto.

32 and at its otherend is pivoted to the frame of the machine at 238.Intermediate of its ends is journaled a roller 239 which projects into acam groove in a disk 240 rigid on the shaft 82. It will be seen that 'byone revolution of the cam'240 the counter will be drawn down over theracks 15 and returned to normal position.'

I .In Fig. 5 the mechanism is shown in norgear 83 meshing with malposition with the operating gear gear 85 which is the main of themachine and is ada ally operated, and gear 8 separated from gear 85.When the rate per unit ke is depressed the rod 73 ismoved forwar thereby oscillating lower link 77. As this link oscillates forwardly itscamslot 78 will force it downwardly, thereby withdrawing gear 83 fromconnection with gear 85, and conhe train of gearof the figure, andincluding the wheels 8 94, 95 and 98 will be thrown into connection withthe main operating gear 85. The gear 98 is rigid on shaft 96 and alsorigid with this shaft are cams 99, see Figs. 6 andlO. These cams 99engage-with anti-frictipn rollers100 projecting from the upper ends oflinks 101, which are connected at their lower ends with the frames 102comprising side arms and connecting rods'103. There is one of theseframes 102 for each bank of keys 5 and theyere rocked by the cams 99 toreturn the previously released controlling bars thereby actuating asub-counter 104l1ereinafter described. The frames 102 are rockedsuccess'ively so as to .insure the entering of the proper amount uponthe sub-counter." The sub-counter 104 is mounted upon a shaft 137 .in aframe 105. This frame as shown in Fig. 5, is adapted to be oscillatedboth forwardly and rearwardly from normal osition by "a box cam 106secured upon a a 96. One end of a link 108 straddles the shaft 96 whilethe other end of said link is connected to the franie '105 above itspivotal oint. An antifriction roller 107 is carried y the limit 108 andprojects into the groove formed in the cam cam groove is such that theframe 105 is first oscillated rearwardly at the topand pose of throwingthe lower part 'of the then forwardly three times and is then moved verymuch farther forward thanbefore and finally returns to normal position.The first three oscillations are for the purframe carrying pinions 59,60 and 61 into mesh with the contro'llin dent that, inasmuch as rame105is journaled'ne'ar its middle on shaft 110, a rearward motion'of the topof the frame will cause a forward motion of the bottom there- I -.ofcarrying the pinions 59, 60 and 61 into engagel nQI! with thezcontrolhng bars 52.

It will understood that each'key conted to be manu- 106. he shape of thebars. Itfzis evi-n trols a number of bars 52 corres the number ofdenominations in t obtained by multiplying the rate per unit by thecapacity of the weighing mechanism. For instance, the 1} cent key'willonly sontro l a single bar 52, as the capacity of the weighing mechanismas shown is limited to 25 pounds, the 5 key will control three bars,namely, the cents, dimes and dollars, while the 40 and 50 cent keys willcontrol bars of four denominations.

As previously described, the frames 102 return the bars 52, controlledby the different banks of keys successively from the I higher to thelower denominations which requires the three oscillations of the frame 1so as to allow the bars 52 controlled byv the keys of the banks of lowerdenominations to return, by gravity or suitable springs to theirpreviously adjusted positions when the pinions 59, and 61 are disengagedfrom the said bars. The cams 99 for returning the bars'52 through meansof the frames 102, are so constructed that as the bars 52'.controlled bythe different banks 'of keys are returned they prevent said ba'rs romdropping below then returned position until other means hereinafterdescribed is brought into play, after which the frames 102 return totheir normal osition;

-.--.,It will be seen from the a ve description and b reference to Figs.2', 7, 10 and 11 that if an article weighlng two ounds and valued at3%?! per pound was p aced upon the scale the determining disks 51 wouldbe rotated to such an extent that when the bars 52 controlled by the 1}and 3c keys, which are the second and third and' the tenth and eleventhones respectively from the left in Fig. 10, representing the units andtens denominations, the units bar controlled by the i and 3 keys woulddrop one and-six spaces respectively while the tens bars controlled bysaid keyswould contact with the periphery) of their corresponding disks51. Now up 11 operating the machine the pinions 59, 60 and 61 Wlll.engage with the controlling bars and the right hand frame 102 in Fig. 10will be rocked to restore-any bars 52 that might have been released. Thelower portion of frame 105 is then moved rearwardly to disengage theinions from the bars 52, after which the rame 105 is drawn forwardly torengage the pinions with the bars and then the mid- .dle restorin frame102 rocked by which movement t 0 units bars 52,, controlled by the 3 keywillbe restored and actuate the sub-counter 104. The pinions 59, 60 and61 are fast upon 'shafts 117,- 118 and 119 respectively and actuate thecents, dlmes and doliars denominations of the sub-counter 104 ashereinafter described. From this it will be seen that as the units bar'52 cononding to, e product trolled by the 3 key is returned, it also Icarries with it the units bar controlled by the key, which, after thepinions are disengaged thesecond timefrom the bars 52, descends to itspreviously adjusted position, while the 3. units bar is held in itsraised position by. the rod 103 in its frame 102 as previouslydescribed. As the pinions 59, 60 and 61' and the bars 52 are engaged forthe third time and the left hand frame 102, as shown in Fig. 10, isr0cked,the 4c units bar will be restored and. actuate the sub-counter104 one space, which in addition to the six spaces added to thesub-counter, by the 3 units bar represents the product of thetransaction. The bars 52 are allowed to move nine spaces in eitherdirection by means of the elongated slots 52.

It will be seen from the above description that if the bars 52 were notreturned suc- .cessively an incorrect registration would be made.

Referring now to Figs. 2, 11 and 12 the connections between thedifferent denominationsof the sub-counter 104 and the pinions 59, 60,.61, 62 and 63 will be described The units bars 52 as previouslydescribed are arranged to be engaged by the pinions 59 secured to theshaft'117. Fast to this shaft is a gear wheel 250, which meshes with pions 60, which are actuated by the tens bars 52, are secured to theshaft 118, the latter having a gear wheel 256 fastened to its left handend,..see Fig. 11, which meshes with a smaller gear wheel 257 secured toone end i of the shaft 110. This shaft is broken as at 110 and near" thecenter of the left hand portion, as shown in Figs, 2 and 10, is secureda gear 258, which meshes with a similar gear 259, secured .to one end ofa sleeve 260 surrounding the shaft 137 The other end of the sleeve 260has fastened thereto the tens denominational wheel of the subcounter104.- The shaft 119, which carries the pinions 61 actuated by the unitsof dollars bars 52, has secured to its right hand end, looking from therear, a gear wheel 261, which meshes, with a smaller wheel 262' securedto the right hand end of the broken shaft 110., The inner end of thispart-of I the shaft has secured to it one end of. a sleeve 263, theotherend of which carries a gear 264 that meshes with'a similar wheel ofthe subcounters. The'sleeve 263also acts as asupport for the inner endof the left hand portion of. thesha'ft 110. The tens of dollars wheel ofthe sub-counter issecuredthat are in turn actuated by the tens ofdollars bars 52. The pinions 62 and 63 as previously described, areloosely mounted upon the shaft 117 and are held from lateral movement bysuitablecollars.

A transfer device indi ated 112 is shown on- Figs. 6 and 11, and thisdiffers from the usual register only in having two sets of transfer cams113. This is rendered necessary by the fact that in some cases twotransfers must take place in one operation "of the machine, which ofcourse never happens in an ordinary adding register. pounds, 14 ounces,at 48 3/4 cents, was made, two transfers would be necessary. As aboveindicated, the amount correspondingto 40 cents would first be added in,this being $9.95. The amount corresponding to 8 cents, being $1.99,would next be added, and a' transfer will evidently here be necessary.When the third amount-to wit, 19 cents, corresponding to the 3/4cent-key, is added, a second transfer will be required. This would alsobe true with many other amounts.

The movement of links 101 to restore the controlling bars 52 is alsoutilized to reset to zero the setting levers 11. As shown in Fig. 5, theleft hand frame 102 is connected by alever 125 to a link 126, which isconnected to and moves a bell-crank lever .127,-

joui-naled on a bar 12 8. This bell-crank lever 127 is part of a frame,including a rod 129, which is normally under the setting levers 11. Whenframe 102 is raised, a clockwise motion of bell-crank 127 is produced,thereby returning the setting levers to the position shown in Fig. 6,which 1s the normal position. When links 101 descend again, theconnections referred to are restored to the position shown in Fig. 5,and levers 11 may again be operated.

When the amounts have been added on the sub-counter .104, it isdesirable to transfer these amounts to the indicating devices 23 of themachine, in order that the operator may obtain the benefit of thecomputation. As'previously stated, the frame 105 is finally-rockedforward at the top by the last depression in box cam 106. Thisservesgenerally by v If, for example, a purchase of 24 to throw the counterWheels 104 into meshwith a series of segment-racks 131, 1ournaled;

loosely on shaft 96. Thesesegment-racks have a second segment 132connected therewith, and these rajcks 132' are adaptedto enga e racks133 on the indicator-operating rac -bars '14. When the counter 104 isthrown into gear with racks 131, and then reset, it is evident thatrack-bars 14 willbe of the shaft 137 carrying the counter wheels 104.Said counter wheels have each a pin proiegting laterally therefrom, withwhich in i s moved position pins on the shaft. 137 are adapted toengage. .See Fig. 7. This longitudinal movement of the shaft is causedby a cam 138 moved with shaft 96, and which engages a bevelon shaft 137and shifts the said shaft just prior to engagement of the setting pinionby segment-rack 140. This rack is rigid with shaft 96, and is shown inFig. 5 in its normal position. When a complete rotation is given ofshaft 96, at the very end of this rotation the segment-rack 140 willgear with pinion 139, which has then been drawn forward, and cause acomplete rotation of same, thereby 80 resetting any of the counterwheels which have been moi'ed forwardly by the controlling bars 52. Thetype of zero setting device referred to is well known in the art. 'Thisfirst part of the operationi also utilized to release the rate keys 55through the movement of the lever 125, as shown in F ig." 5. When links101 are raised, lever 125 is rocked rearwardly and engages and moves alever 147, rigid on shaft 148 This shaft, as shown in Fig. 6, has alsori id therewith a lever 149 connected to the detent-locking bar 70,above referred to. A rearward movement of this bar will release thedetent bar 68, and allow the keys55 to rise under the influence of theirsprings. The release of the keysallows the bars 58 to move rear- .wardunder the tension of springs 1.50, and bar 70 will then reset the rod73, thereby ungearing gear-wheel 87 from gear-wheel 85, and throwinggear 83 into connection,therewith. This, however, doesnot take placeuntil a complete rotation of main-operating gear 85, owing to a flange151 carried by said. gear. .When-lever 77 is depressed to 5'5 carry gear87 into. mesh with gear 85, a pin 152, movable with the said lever, iscarried downwardly through anotch in flange 151. When pinion '85 is thenrotated, the flange f 151 passes over. piii 152 and holds it depresseduntil a complete rotation of pinion 85,. when it is again allowed torise. This is rendered necessary by the factthat the rate keys arereleased a, r a half rotation of the operating handle, in order thatsupports 53 may engage under the con- The means for resetting the dollarpinions 61 and dimes engaged and. moved by the return of the vdimes-controlling bars 52. The eents-conq may be left in this setposition until a second computation is to be made. The placing of thesecond weight onthe scale pan 41 andturning the handle once more willindicate the-new product, inasmuch .as the :setting levers 11 and theregister-operating racks 14 are reset to normal position at eachoperation.

The operation of the device; as thus far.

described, will be as follows: Suppose a weight of 17 pounds is placedon the scale, and it is desired to compute the value'of this quantity at313/4 cents, the operation will-comprise the placing of the. weight onthe scale pan 41 and depression of the rate per unit keys 55,corresponding to 30 cents, to one cent,- and to three-fourths of a cent,and one turn of the operating handle. When the weight is placed on thescale pan 41, lever 42 will be rocked around its pivot at knife edge 44and cause a rotation of shaft 50, carrying the amount determining disksshown in Fig. 2. This shaft and the disks thereon will rotated 17/25thsof a' complete rotation. The depression of the three rate .per unit keysWlll then release the corresponding supports 53 for the controlling bars52 by moving levers 58 for; wardly. The keys will beheld in depressedposition by the forward movement of bar 70, which is permitted when thedetent 68 moves to the left, as shown in Fig. 4. The

forward motion of levers 58 will move bar 73, and through the cam deviceshown in Fig. 5 will lower the two gears 83 and 87,."

thereby bringing gear 87 into mesh with' the main operating gear 85',and connect the computing devices to the operating handle. I

The operating handle'is then given one complete rotation. The first partof the rotation will raise the link 101, correspondingto the dimes keys,and thereb restore the controlling bars 52, which have been released bythe 30-cent key. .At this time the frame 105 has been rocked forwardlyat the lower end by the box cam 106, in Fig. 5', and the p nions 60 aretrolling bars 52, and the fractions of cents bars are returnedsuccessively, and between these two returns, and after thelatter return,the frame 105 is rocked rearwardly at i the lower end twice to allow thetransfers pointed out above that in the operation of this machine twotransfers would frequently be required in succession. \Vhen thefraction-frame 102 is raised, lever 125 will be rocked, and through thebell-crank 127 and bar 129 will raise the levers 11 to the positionshown in Fig. 6, thereby resetting the register-controlling devices tonormal position. As lever 125 rocks rear- Wardly, it abuts the lever14:7 and thereby releases the keys, but rearward movement of the rod 73is prevented until a complete rotation of the gear 85 through the flange151 and pin 152. During the second half of this complete rotation,counter shaft 137 is slid longitudinally by the cam and bevel referredto, thereby bringing the resetting pins on said shaft into register withthe pins of the counter-wheel. Frame 105 is then rocked forward by thelast depression in box-cam 106, to bring the pinion 13.9 on

- counter-shaft 137 into mesh with segmentgear 140. This causes acomplete rotation reversely of counter-shaft 137, and the counter-wheels104 are thereby picked up and returned to zero. As they are at this timein gear with segments 131, the amount previously indicated on thecounter is caused to be now set up .on the indicating-devices of the"cash register, and this also causes movement of the setting levers 11and rackbars 14 to a corresponding position. The clerk may now read thecomputed product on the indicating disks 23. If the transaction is notcompleted the machine may be left in this position, and when a secondcomputation is to be made. it will not need to be reset, inasmuch as thesetting handles 11 and other register-controlling devices areautomatically reset to normal position during each computation. If, onthe other hand, the transaction is to be entered in the cash register,all that is necessary is to give the operating-gear 85two additionalrotations, as is the case when the cash register is used alone.\ As atthis time gear 85 will be in mesh with the large gear 83, shaft 82,

which is the main operating shaft of the cash register,.will be given acomplete rotation. This will cause counter 31 to be reciprocated overthe racks 15, and the transaction will be entered on the said counter.

As hitherto stated, there is provided what may be termed an alternativecontrolling means for the computing devices which may beusedin'ca-ses'involving the computa-- tion of other things besides aweight. The parts of the machine referred to' are best shown in Figs. 2,8 and 9. In Fig. 8 is showh a disk 191, having a plurality ofgraduations and a set of ratchet-teeth, one or each graduation. Apointer 192 is J adapfiad tomove over the graduations, and

carries a pawl 193 adapted to engage,the

. 206 will engage ratchet-teeth to prevent reverse rotation. This pawl193 is pivoted on a pin 194 on the said pointer, and is normally forcedoutward by a spring 195, connected at one end to the pointer, and at theother end to a sliding bar 196. This bar is pivoted at its outer end tothe pawl 193, and at its inner endis connected to a bar 197 by a pin andslot connection, which will allow the bar 196 and pawl 193 to ratchetover the teeth of the disk 191 without disturbing the bar 197. At theinner end of the bar 197 is a slot 198, embracing a vertical pin 199,having a cam part 200. When the pointer 192 has been rotated, and pawl193 engages some one of the ratchet-teeth on disk 191, the pointer willbe held in set position against the tension of a spring 201, whichnormally tends to return the said pointer to zero position. During theoperation of the machine the pin 199 is depressed, and its cam part 200thereby forces bar 197 toward the center, releasing pawl 193 from theratchet on disk 191, andpermitting spring 201 to automaticallyrese't-the pointer. This pointer 192 is connected with a bevel gear 203,gearing with a second beveled gear-204, rigid with shaft 50*, whichbears the controlling disks 51. It will therefore be evident thatmovement of the pointer will cause the same effect on the controllingdisks 51 as will the placing of a weight on the scale-pan. In orderto-prevent movement of the scale when the quantity indicator isemployed, and vice versa, to prevent movement of the quantity indicatorwhen the scale is used, there is provided an interlocking means. It willbe seen from Fig. 8 that pointer 192 is provided with a cam 206, whichis adapted when the pointer is moved from normal position to engage abar 207, andmove the same laterally. This bar is carried inthe center ofshaft 50% and is connected thereto by a pin-and-slot connection 208, soas to rptate with the shaft 50*, but to be susceptible of a slightlongitudinal motion separately therefrom. the other end of shaft 50 thesaid shaft isprovided with a squared shoulder. When the quantityindicator 192 is moved, its cam the beveled end of the bar 207, andforce it toward the right in Fig. 2, thereby throwing the shoulder 209of the shaft 50 into a squared notch 210 in the supporting frame. lheshaft 50* is .not made all in one piece, but is separated at the point211 with a tongue and groove connection between the two parts. Thedividing of the shaft 50 is to enable the setting of the disks 51 by therotation of the'quantity indicator independently of the Weighingmechanism. Upon the return of the quantity indicator to normal or zeroposition the left hand end'of the bar 207 ('Fig. 2) will be shifted backinto.

engagement with the camming'portion of iso a .0 A4 l' indicate t'o theoperatorv the computed which surrounds the shaft 50 and having its endsabutting against the pin of the pin and slot connection 208 and a bossof the machine frame, the right hand portion of the shaft 50 beingreturned into engagement with the other portion of the shaft bearing thedisks 51 by suitable connection with the right hand. end of the bar 207movable therein. The gear 203 has a portion of its teeth cut away as at203* (Fig. 8) so that whem the shaft 50 is rotated by the weighingmechanism the quantity indicator will not be affected. This lateralmotion of bar 207 will therefore throw shoulder 209 into the notch 210and lock thesc'ale-pan and the devices operatedthereby, but will notprevent the rotation of. the determining disks 51 from the quantityindicator. If, on the other hand, an operation with the scale isdesired, the rotation of the pinion 49 will rotate the sqgared shoulder209, so that it will then be impossible to move the quantity indicator,inasmuch as a movement thereof.

I would necessitate the longitudinal shift of the rod 207, but this willbe prevented by the squared shoulder 209 being out of register with thenotch 210. This construction evidently provides for the interlockingabove referred to.

As a means of operating the pin 199 to release the quantity indicatorand allow it to be returned to zero, there is shown a lever 211connected by a pin-and-slot connection to alever 212, mounted on shaft148, this shaft being also shown in Fig. 5, and it will be rememberedthat the rearward movement of link 126 for the purpose of resetting thesetting levers alsoserves to'rock this lever 147. Such rocking willevidently also rock the lever 212 and cause adepression of pin 199,thereby, releasing the pawl 193 from the ratchet on disk 191. The spring201 will then immediately return the pointer 192 and the controllingdisks 51 to normal position. hgsThe operation of the machine asdescribed been quite fully stated heretofore, and

tion.

It will be seen from the previo is description that the desired objectsare attained in a very satisfactory manner b I this mechabe used in-theordinary way by setting the handles 11 ti) the desired amount, and thengiving the will, it is thought, be clear from-"the descrip- 'mainoperating handle two complete rotations. If, however, a computation ofweight is desired, the mere lacing of the article on of the properrate'per unit keyzor iiiand one turn. of t pirating han 1e will thescale-pan, toget er with the depressions ind'iifi amount, and will alsoplace the controlling devices of the cash register in position forsired, the mere movement of the quantit pointer will disconnect thescale and wil control the computing in exactly the same manner as thescale is intended to do.

Fig. 3 shows a device for reventing continued oscillation of the scal dbeam 42 during the operation of the accounting mechanism. Such deviceconsists of means for intermittently and lightly interrupting theoscillation of the beam; A pad 231 is mounted on one end of-the lever.232 and in position to engage a disk 233 on the shaft 50". The shaft 50of course oscillates with the scale beam 42 so that when the pad 231 isbrought into contact with the disk, oscillation of the shaft 50 will bechecked. A toothed disk 234 is rigidly mounted on the shaft 96 andcoacting with the teeth on said disk is a. roller 235 which is mountedon a link 236. One end' of the link 236 is con- 4 nected to the lever232, so of course when -th1s bar is an arm 229 (Fig. 5) adapted to bedepressed by a cam 230 rigid on the shaft 96. It will be clear that whenthe shaft 96 is rotated by turning the main handle, the bar 227 will berocked and its uared shoulder moved out of the pathv o projections 228.The bars 52 which have been released by the depression of rate keys 58will then drop to ositions depending upon the posi- --tion of t e disks.

While the form of'mechanism here shown and described is admirablyadapted to fulfil the objects primarily stated, it is to be understoodthat it is not intended to confine the invention to the one form ofembodiment herein disclosed, forv it is susceptible of Fig. 6 is shown abar 227, which has 9.
